+ * or as quickly as the application an be repainted, whichever is
+ * slower). For this reason, is most suitable for handling graphics
+ * that change every frame or every few frames. The tick callback does
+ * not automatically imply a relayout or repaint. If you want a
+ * repaint or relayout, and aren't changing widget properties that

+ * trying to display isolated frames at particular times.
*
- * This function is primarily used in widget implementations, and
- * isn't very useful otherwise. Many times when you think you might
- * need it, a better approach is to connect to a signal that will be

+ * frame). gtk_widget_queue_draw() will also end up requesting a frame
+ * on the appropriate frame clock.
+ *
